Sucking on fingers, pacifiers or other objects when children are young is completely normal and can provide a sense of security. Most children naturally outgrow this habit between 2 and 4 years old. Thumb- and pacifier-sucking habits that go on for a long period of time can create crowded, crooked teeth or bite problems. If the habit continues while the permanent teeth erupt, we will assist you in helping the child break the habit with behavioral modification techniques. If that proves unsuccessful, we may suggest an orthodontic-type appliance to help your child break the habit. Most children stop these habits on their own.
